I am 73 years old and had been very active. The blood specialist checked my blood and the iron level was a low 5.4. While I was waiting to get an iron infusion, the FloraVital was recommended. After taking for two days, I noticed a decided increase in my energy level (before getting the infusion!). Now I am a believer! I am continuing to take this wonderful tonic even after my iron level has increased to keep the level high. It's black gold in a bottle!
